Conclusion: I bought these JBL speakers and hope they will be what I wanted... I mounted them in my 18 speed boat that we run on the Hudson river in NY. I am powering them with a JL 500 watt amp and soo far great !!!
Summary: These speakers sound GREAT! They are high quality speakers and as I am going 40MPH and the wind is roaring on the boat along with my twin engines these speakers are still pumping above it all! I highly recommend these speakers to any boater!
Summary: I recently bought 2 sets of these and a set of 6200 series 6.5" speakers. I hooked the 6.5" speakers off the head unit (4x40 watt) and a very noticeable change from the factory speakers. THen i installed a 6x9 under each couch on my party barge and hooked all 4 to a 250 watt Pioneer amp(2 per channel) . All I can say is wow! I like my music loud and clear with a noticeable bass sound. These speakers did more then i expected, sounds like i have a sub and i dont.
